    摘要: There is disclosed a video encoder and corresponding method for encoding video data for an image block. The video encoder performs a mode decision by performing initial motion estimation on only a subset of possible block sizes to output motion information corresponding thereto, and determining, based upon the motion information corresponding to only the subset of possible of block sizes and upon other image-related analysis data, whether other block sizes are to be evaluated.

    摘要: There are provided video encoders and corresponding methods for performing fast mode decision of B-frames. A video encoder for encoding video data for a B slice that is divisible into macroblocks includes an encoder (OO) for performing mode selection when encoding a current macroblock in the B slice by counting a number of neighboring macroblocks in the B slice coded in a DIRECT mode, and only checking one of the DIRECT MODE or a 16×16 mode for the current macroblock when the number of neighboring macroblocks coded in the DIRECT mode exceeds a predetermined threshold.

    摘要: A video encoder is disclosed, the encoder for encoding image frames that are divisible into macroblocks. The video encoder includes means for generating a QP estimate for the macroblocks of an image frame. The video encoder further includes means for selection of a frame level quantization parameter (QP) for the image frame, using one of mean, median, and mode of QP estimates for the macroblocks. A method for encoding video is disclosed for encoding image frames that are divisible into macroblocks. The method generates a quantization parameter (QP) estimate for the macroblocks of an image frame and selects a frame level QP for the image frame, using one of mean, median, and mode of QP estimates for the macroblocks.
